Program-controlled Single Phase Phantom Load Power Source
1 . Setting up and taking the load regulation of voltage, current, phase and frequency of the power factor
2 . Amplitude 2nd-128th phase harmonics, and it can be added to the fundamental wave in every harmonic output
3 . A wide range output of voltage and current, big power, high stability, small waveform distortion degree
4 . Strong load ability, taking capacitive load, sensibility load, resistive load or composite load, load regulation is higher than 0.01%
5 . Applying the 32-bit MPU + DSP + FPGA, powerful flexible;
6 . Using hardware PID, fast response, the change of load will not cause volatility output.
7 . Power frequency waves reach up to 50000 points a week of the wave kneading, signal output without filter, precise waveform output, precise harmonic output, small harmonic distortion degree
